Description

Technical Field

[0001] This invention relates to the field of cable mica tape wrapping machine technology, and particularly to a cable mica tape wrapping machine. Background Technology

[0002] The mica tape wrapping machine is a key piece of equipment in the wire and cable manufacturing industry. It is mainly used to wrap mica tape around the surface of the cable in a specific manner, forming a mica tape-wrapped cable with properties such as insulation, high temperature resistance, and aging resistance. Its core function is to improve the electrical insulation performance and mechanical protection capabilities of the cable through an automated wrapping process, meeting the requirements for safe operation of the cable in different scenarios. This equipment is widely used in power transmission, rail transportation, new energy (such as wind power and photovoltaics), aerospace, and industrial automation, and is especially suitable for the production and processing of high-voltage cables, special cables, and high-temperature resistant cables. It is a crucial link in ensuring the quality and performance of cable products.

[0003] With the development of industrial technology, traditional cable wrapping machines have gradually revealed problems such as limited functionality and insufficient adaptability. Existing equipment mostly adopts a single production line design, resulting in limited processing efficiency. Furthermore, the fixed position of the wrapping mechanism makes it difficult to adapt to cables of different diameters, leading to low equipment versatility. In addition, during the fixed-length cutting process, problems such as loosening of the mica tape and cable breakage are prone to occur at the cut, affecting the stability of the product in subsequent use. Therefore, designing a cable mica tape wrapping machine with high-efficiency production, multi-specification adaptability, and fixed-length cutting capabilities is particularly necessary.

[0022] Reference Figures 1-8 A cable mica tape wrapping machine includes a machine body 1, a first wire 2 and a second wire 3 disposed inside the machine body 1, and mica tapes 4 and 5 wound on the first wire 2 and the second wire 3. A conveying mechanism 6 and a conveying mechanism 7 are installed on the machine body 1, which are used to convey the first wire 2 and the second wire 3 respectively. A winding mechanism 8 and a winding mechanism 9 are disposed inside the machine body 1, which respectively wind the mica tape 4 and the mica tape 5. The conveying mechanism 1 (6) and conveying mechanism 2 (7) are mainly conveying rollers and guide rollers. They convey line 1 (2) and line 2 (3). It should be noted that in order to prevent line 1 (2) and line 2 (3) from interfering with each other when conveying and winding mica tape 1 (4) and mica tape 2 (5), a figure-eight guide roller is set inside the machine body 1. This roller can adjust the conveying height of line 2 (3) to make a certain height difference between line 2 (3) and line 1 (2), thereby avoiding interference when the two are wound at the same time.

[0023] An unwinding device 10 is provided on one side of the machine body 1. The unwinding device 10 includes a frame 101, an unwinding roller 102 and an unwinding roller 103 rotatably connected to the frame 101. The unwinding roller 102 and the unwinding roller 103 are used to store mica tape 4 and mica tape 5, respectively. The unwinding device 10 is a passive unwinding device, and the mica tape 4 and mica tape 5 can be loaded onto the unwinding roller 102 and the unwinding roller 103 for use.

[0024] The winding mechanism 8 includes a fixed frame 81 mounted on the inner bottom wall of the machine body 1, a servo motor 82 mounted on the fixed frame 81, a drive gear 83 mounted on the output end of the servo motor 82, a driven gear 84 meshing with the drive gear 83, a slide groove 85 formed on the driven gear 84, an electric linear guide rail 86 mounted on the inner wall of the slide groove 85, a winding roller 87 slidably connected to the electric linear guide rail 86, and a sleeve 88 mounted on one side of the driven gear 84. One end of the mica tape 4 is fixedly connected to the outer wall of the winding roller 87. A limit groove 15 is formed on the inner wall of the sleeve 88, and the inner wall of the limit groove 15 is rotatably connected to... A limiting ring 16 is provided, and a support sleeve 17 is fixedly connected to the inner wall of the limiting ring 16. The support sleeve 17 is fixedly connected to the driven gear 84. A support rod 18 is symmetrically fixedly connected to the outer wall of the sleeve 88. The other end of the support rod 18 is fixedly connected to the inner side wall of the machine body 1. The support rod 18 is used to support the sleeve 88 and ensure the stable rotation of the driven gear 84. The structure and working principle of the winding mechanism 2 9 are consistent with the structure and working principle of the winding mechanism 1 8. Mica tape 1 4 and mica tape 2 5 are wound onto the outer walls of yarn 1 2 and yarn 2 3, respectively. The specific operation of winding mica tape 1 4 onto yarn 1 2 will be described in detail below. During the conveying process of line 2, the servo motor 82 of the winding mechanism 8 is simultaneously activated. The servo motor 82 drives the drive gear 83 to rotate. The drive gear 83 meshes with the driven gear 84, thereby driving the driven gear 84 to rotate. The rotation of the driven gear 84 drives the winding roller 87 to rotate. One end of the mica tape 4 is mounted on the winding roller 87, so the rotation of the winding roller 87 drives the mica tape 4 to rotate around the outer wall of line 2, thus winding the mica tape 4 to the outer wall of line 2. It should be noted that the unwinding roller 102 is the driven end, and the servo motor 82 drives the driven gear 84 through the drive gear 83. Rotation is the driving end, and the center line of the driven gear 84 is on the same straight line as the center line of the first 2 of the line. Thus, the winding roller 87 can wind the mica tape 4 to the outer wall of the first 2 of the line. The distance between the winding roller 87 and the first 2 of the line can be adjusted by the electric linear guide rail 86. Thus, within a certain adjustment range, the mica tape 4 of the first 2 of the line with various diameters can be wound. It is convenient to use. The final state of the first 2 of the line and the second 3 of the line after winding is the mica tape wrapped line. The mica tape wrapped line mentioned below refers to the complete body of the first 2 of the line with the first 4 of the mica tape (and the second 5 of the mica tape has been wound to the second 3 of the line).

[0025] The cutting mechanism 12 includes an electric linear guide rail 121 mounted on the base 11, a slide plate 122 slidably connected to the electric linear guide rail 121, a cylinder 123 mounted on the slide plate 122, and an electric cutting clamp 124 mounted on the output end of the cylinder 123. The electric cutting clamp 124 is used to cut wire body 2 and wire body 3. The electric cutting clamp 124 of the cutting mechanism 12 can cut the mica tape wrapped wire in the final assembled state to a fixed length. The electric cutting clamp 124 is an existing structure, so its working principle and structure will not be discussed in detail.

[0026] A hot-press fixed-length cutting device is installed on one side of the machine body 1. The hot-press fixed-length cutting device includes a base 11, a cutting mechanism 12 mounted on the base 11, a hot-pressing mechanism, and a laser Doppler sensor 14 for detecting the length of line 1 2 and line 2 3. The cutting mechanism 12 is used to cut line 1 2 and line 2 3, and the hot-pressing mechanism is used to reinforce the cut ends of line 1 2 and line 2 3. The hot-pressing mechanism includes an electric linear guide rail 3 131 mounted on one side of the electric linear guide rail 2 121, a slide plate 2 132 slidably connected to the electric linear guide rail 3 131, a cylinder 2 133 mounted on one side of the slide plate 2 132, and a hot-pressing assembly 134 mounted on the output end of the cylinder 2 133. The hot-pressing assembly 134 includes... Includes a hollow arc-shaped support 1341 fixedly connected to the output end of cylinder 2 133, an arc-shaped toothed plate 1342 installed on the inner wall of the hollow arc-shaped support 1341, guide grooves 1343 installed on the inner walls of both sides of the hollow arc-shaped support 1341, a moving rod 1344 slidably connected to the inner wall of the guide groove 1343, a meshing gear 1345 fixedly connected to the outer wall of the moving rod 1344, a drive motor 1346 installed at one end of the meshing gear 1345, a connecting frame 1347 fixedly connected to one end of the central shaft of the meshing gear 1345, a drive motor 2 1348 installed on the connecting frame 1347, a positive and negative thread screw 13401 located at the output end of the drive motor 2 1348, and a threaded connection to the positive and negative thread screw. The hot pressing plates 1349 and 1340 on the lead screw 13401 are connected by a meshing gear 1345 and an arc-shaped toothed plate 1342. After the hot pressing mechanism is in place, the drive motor 1348 is started to drive the lead screw 13401 to rotate, driving the hot pressing plates 1349 and 1340 to move towards each other. Because the hot pressing plates 1349 and 1340 are restricted by the through slot opened in the connecting frame 1347, they can only move up and down on the outer wall of the lead screw 13401 to press against the outer wall of the mica tape wrapping wire, avoiding breakage at the ends during cutting and loosening. After a certain period of hot pressing, the drive motor 1348 is started again to make the hot pressing plates 1349 and 1340 move in opposite directions. Stop the hot pressing reinforcement, then start the drive motor 1346 to drive the meshing gear 1345 to rotate, meshing with the arc-shaped toothed plate 1342, driving the moving rod 1344 to rotate and move within the guide groove 1343. At the same time, the connecting frame 1347 makes a circular motion as a whole. Because the center lines of the hollow arc-shaped support 1341 and the arc-shaped toothed plate 1342 are collinear with the center line of the mica tape wrapping wire, the connecting frame 1347 makes a circular motion on its outer wall. Adjust the positions of the first hot pressing plate 1349 and the second hot pressing plate 1340 to the two sides that have not been hot pressed and reinforced. Start the drive motor 1348 again, and the first hot pressing plate 1349 and the second hot pressing plate 1340 move towards each other to perform hot pressing. Hot pressing reinforcement prevents the ends from breaking and loosening, improving the practicality and convenience of the equipment.

[0027] The electric linear guide rail 2 121 and the electric linear guide rail 3 131 are set at right angles, and the laser Doppler sensor 14 is mounted on the slide plate 2 132. The laser Doppler sensor 14 can detect the length of the mica tape wrapping wire in real time. The laser Doppler sensor 14 is an existing structure, so its structure and working principle will not be discussed in detail.

[0028] It also includes a PLC control cabinet and an automation control system. The PLC control system is installed on the machine body 1 near the conveyor mechanism 7, and the automation control system is installed inside the PLC control cabinet. The automated operation of the equipment is realized through the PLC control cabinet and the automation control system.

[0029] Working principle: Line 1 (2) and Line 2 (3) are wound onto conveying mechanism 1 (6) and conveying mechanism 2 (7) respectively. Line 1 (2) and Line 2 (3) are then wound onto the guide rollers located at the inlet and outlet of machine body 1, and conveyed by the guide rollers. The other ends of Line 1 (2) and Line 2 (3) are mounted on two external winding devices. First, the two external winding devices are started, which pull Line 1 (2) and Line 2 (3) to move. Line 1 (2) and Line 2 (3) are driven by conveying mechanism 1 (6), conveying mechanism 2 (7) and guide rollers. The second step involves winding mica tape 4 and mica tape 5 onto the outer walls of yarn body 2 and yarn body 3, respectively. The specific operation of winding mica tape 4 onto yarn body 2 is described in detail below. During the conveying of yarn body 2, the servo motor 82 of the winding mechanism 8 is simultaneously activated. The servo motor 82 drives the drive gear 83 to rotate. The drive gear 83 meshes with the driven gear 84, thereby driving the driven gear 84 to rotate. The driven gear 84 rotates, causing the winding roller 87 to rotate. One end of mica tape 4 is mounted on the winding roller 87, so the rotation of the winding roller 87 causes mica tape 4 to rotate around the outer wall of yarn body 2, thus winding mica tape 4 onto yarn body 2. Regarding the outer wall, it should be noted that the unwinding roller 102 is the driven section, and the servo motor 82 drives the driven gear 84 to rotate through the driving gear 83 as the driving end. The center line of the driven gear 84 and the center line of the line body 2 are on the same straight line, so the winding roller 87 can wind the mica tape 4 to the outer wall of the line body 2. The distance between the winding roller 87 and the line body 2 can be adjusted by the electric linear guide rail 86, so that the mica tape 4 can be wound on the line body 2 of various diameters within a certain adjustment range, which is convenient to use. The way the mica tape 25 is wound onto the line body 2 is the same as the way the mica tape 4 is wound onto the line body 2, so it will not be discussed in detail. The third step is fixed-length cutting. Taking the final state of mica tape 4 wound onto wire 2 as an example, the cutting method is the same as that for mica tape 4 wound onto wire 2. The final state of the wire is a mica tape wrapped wire. The mica tape wrapped wire mentioned below refers to the complete form of mica tape 4 already wound onto wire 2 (mica tape 5 already wound onto wire 2 3). After a certain length of mica tape wrapped wire is wound on the external winding device, when it is necessary to cut the mica tape wrapped wire beyond the fixed length from the previous fixed length, the laser Doppler sensor 14 can monitor the length of the mica tape wrapped wire in real time. When a certain length is reached... The laser Doppler sensor 14 transmits signals to the PLC control cabinet. The PLC control cabinet controls the electric linear guide 121 to start adjusting the height of the electric shears 124. The cylinder 123 starts adjusting the position of the electric shears 124, moving it to the outer wall of the mica tape wrapping wire. Then, the cylinder 133 is driven to start adjusting the height of the hot pressing mechanism, aligning its centerline with the centerline of the mica tape wrapping wire. The electric linear guide 131 is then driven to move the hot pressing mechanism to the outer wall of the mica tape wrapping wire. It should be noted that cylinders 123, 133, 121, and 131 all have built-in position detection sensors, enabling precise positioning under the control of the PLC control cabinet. Then, the second drive motor 1348 is started to drive the positive and negative threaded screw 13401 to rotate. The rotation of the positive and negative threaded screw 13401 drives the hot pressing plates 1349 and 1340 on its outer wall to move towards each other. Because the hot pressing plates 1349 and 1340 are restricted by the through slots opened on the connecting frame 1347, they can only move up and down on the outer wall of the positive and negative threaded screw 13401, and will not rotate synchronously with the positive and negative threaded screw 13401. Thus, the hot pressing plates 1349 and 1340 are pressed against the outer wall of the mica tape wrapping wire to prevent the end from breaking during cutting and causing the mica tape wrapping wire to loosen. After the upper and lower outer walls have been pressed for a certain period of time, the second drive motor 1348 is started again to drive the hot pressing plates 1349 and 1340 through the positive and negative threaded screw 13401. 349 and the second hot press plate 1340 move in opposite directions, thereby stopping the hot pressing reinforcement of the mica tape wrapping wire. Then, the drive motor 1346 is started to drive the meshing gear 1345 to rotate. The meshing gear 1345 meshes with the arc-shaped toothed plate 1342, so the meshing gear 1345 rotates and moves on the arc-shaped toothed plate 1342. At the same time, the rotation and movement of the meshing gear 1345 drives the moving rod 1344 to rotate and move on the inner wall of the guide groove 1343. Simultaneously, the rotation and movement of the meshing gear 1345 drives the connecting frame 1347 to perform a circular motion as a whole. Since the center lines of the hollow arc-shaped support 1341 and the arc-shaped toothed plate 1342 are on the same straight line as the center line of the mica tape wrapping wire, the connecting frame 1347 performs a circular motion on the outer wall of the mica tape wrapping wire.The positions of the first hot press plate 1349 and the second hot press plate 1340 are adjusted by rotating the connecting frame 1347, so that the first hot press plate 1349 and the second hot press plate 1340 are located on the other two sides of the mica tape wrapping wire that are not hot-pressed and reinforced (i.e., the left and right directions of the outer wall of the mica tape wrapping wire). Then, the second drive motor 1348 is started again to drive the positive and negative threaded screw 13401 to rotate. The rotation of the positive and negative threaded screw 13401 drives the first hot press plate 1349 and the second hot press plate 1340 on its outer wall to move towards each other, so that the first hot press plate 1349 and the second hot press plate 1340 are in contact with the mica tape wrapping wire. The outer wall of the mica tape wrapping wire is heat-pressed. There are two sets of heat-pressing mechanisms, both using this method; therefore, the working principle of the other set of heat-pressing mechanisms will not be discussed in detail. After heat-pressing reinforcement, the electric shears 124 are activated to cut the mica tape wrapping wire, thus achieving fixed-length cutting. The heat-pressing method effectively reinforces the two ends of the cut mica tape wrapping wire, preventing breakage at both ends and thus avoiding loosening of the mica tape wrapping wire. This improves the practicality and convenience of the equipment.

[0030] This equipment can simultaneously wind mica tape 4 and mica tape 5 onto line 1 (2) and line 2 (3), creating two independent production lines. Compared to existing equipment with only one winding and conveying production line, this significantly improves processing efficiency. Furthermore, winding mechanisms 1 (8) and 2 (9) can adjust the distance between the winding roller 87 and line 1 (2) (or line 2 (3), thus adapting to various diameters of line 1 (2) (or line 2 (3) within a certain adjustment range. This effectively enhances the equipment's practicality. Additionally, it can perform fixed-length cutting of the wound mica tape, meeting different processing needs within a certain range and improving the equipment's ease of use.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
