Description
Technical Field
[0001] This utility model relates to the field of battery sleeve production technology, specifically to a continuous production equipment for fire-resistant material battery sleeves. Background Technology
[0002] Fire-resistant battery sleeves are components used to protect batteries, typically made of fire-resistant materials. They can, to some extent, prevent external fire sources from reaching the battery, slow the spread of fire, and reduce the probability of the battery exploding or burning due to fire, ensuring battery safety in fire scenarios. They can also prevent physical damage to the battery, such as scratches and impacts, and provide some moisture and dust protection, helping to maintain battery performance and lifespan. Common materials include ceramic fiber, glass fiber, and fire-resistant plastics. These materials have good high-temperature resistance, flame retardant properties, and a certain degree of mechanical strength. The production of fire-resistant battery sleeves now requires specialized manufacturing equipment.
[0003] Based on the above, the inventors have discovered the following problems: Current production equipment generally uses a sewing machine body to sew the upper fireproof material, fiberglass, and the two sides of the lower fireproof material to form a battery cover substrate. However, during the sewing process, since the position of the sewing machine body is fixed and the width of the material varies, the position of the sewing machine body cannot be adaptively adjusted according to the different width dimensions of the material, thereby reducing the practicality of the production equipment.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a continuous production equipment for fireproof battery sleeves, in order to achieve a more practical purpose. Utility Model Content
[0005] The purpose of this invention is to provide a continuous production equipment for fire-resistant battery sleeves to solve the problems mentioned in the background art.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0007] A continuous production line for fire-resistant battery sleeves includes an unwinding assembly, a winding assembly, a sewing assembly, and a pressing assembly. The sewing assembly is located outside the unwinding assembly, the winding assembly is located outside the sewing assembly, and the pressing assembly is located above the sewing assembly. The sewing assembly includes a sewing table, with mounting grooves at both ends. The two mounting grooves are staggered, and an adjustment platform is installed inside each pair of mounting grooves. A sliding groove is provided inside each of the two adjustment platforms, and an electric slide rail is installed inside each of the two sliding grooves. An electric slider is slidably connected to the outside of each of the two electric slide rails. A sewing machine body is mounted on the upper end of each of the two electric sliders. A mounting base is mounted on the opposite end of each of the two sewing machine bodies, and an edge detection sensor is mounted on the bottom end of each of the two mounting bases.
[0008] Furthermore, an embedding groove is provided in the center of the sewing table, and a pressure plate is provided at the upper end of the sewing table directly above the embedding groove. Both ends of the pressure plate are upturned, and connecting strips are installed on the outer walls of both ends of the pressure plate. The connecting strip is fixedly connected to the top surface of the sewing table at the end away from the pressure plate, and the connecting strip is upturned at the end near the pressure plate.
[0009] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the embedding groove, pressure plate and connecting strip, since both ends of the pressure plate are raised upwards, the upper fireproof material, glass fiber and lower fireproof material that are easy to press move forward through the space between the left end of the pressure plate raised upwards and the embedding groove to the space between the middle of the pressure plate and the embedding groove. At this time, the upper fireproof material, glass fiber and lower fireproof material are tightly attached in the space between the middle of the pressure plate and the embedding groove. The two sides are respectively sewn by two sewing machine bodies. The sewn strip battery sleeve moves forward through the space between the right end of the pressure plate raised upwards and the embedding groove until it is rolled up.
[0010] Furthermore, the pressing assembly includes two pairs of seats, which are respectively installed on the upper sides of the sewing table. A fixing block is installed inside the two pairs of seats near the bottom. A first rotating roller is rotatably connected between the pair of fixing blocks on the same side. A moving block is slidably provided inside the two seats above the fixing block. A second rotating roller is rotatably connected between the pair of moving blocks on the same side.
[0011] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the first rotating roller and the second rotating roller, a stable upper and lower pressing force is formed on the upper fireproof material, glass fiber and lower fireproof material. When the material is conveyed to the sewing area, it can effectively prevent the material from shifting or slipping, and ensure that the material remains flat during the sewing process.
[0012] Furthermore, both of the square seats have sliding grooves on both sides of the inner wall above the fixed block. Sliding strips are slidably connected inside the sliding grooves. One side of the sliding strip is fixedly connected to one side of the moving block. Both of the square seats have threaded holes inside the upper end. A screw is threaded inside the threaded hole. The bottom end of the screw is connected to the side of the moving block away from the fixed block through a bearing. A knob is installed on the end of the screw away from the moving block.
[0013] The beneficial effect of adopting the above-mentioned further solution is that by rotating the knob to drive the screw to rotate, the height of the moving block and the second rotating roller can be adjusted, thereby adjusting the distance between the first rotating roller and the second rotating roller, adapting to fireproof materials of different thicknesses. At the same time, the cooperation between the slide bar and the slide groove makes the moving block rise and fall stably.
[0014] Furthermore, the unwinding assembly includes an unwinding table, which is installed on one side of the outer wall of the sewing table. A first air shaft is rotatably connected to one side of the inner wall of the unwinding table. A second air shaft and a third air shaft are rotatably connected to the inner wall of the unwinding table on the side of the first air shaft. The second air shaft and the third air shaft are arranged sequentially from top to bottom.
[0015] The beneficial effect of adopting the above-mentioned further solution is that, through the coordinated use of the first air expansion shaft, the second air expansion shaft, and the third air expansion shaft, the glass fiber core is fitted onto the first air expansion shaft, and the upper fireproof material core and the lower fireproof material core are fitted onto the second air expansion shaft and the third air expansion shaft, respectively. During the battery sleeve production process, the upper fireproof material, glass fiber, and lower fireproof material can be unwound synchronously. At the same time, the first air expansion shaft, the second air expansion shaft, and the third air expansion shaft facilitate the installation of the glass fiber core, the upper fireproof material core, and the lower fireproof material core.
[0016] Furthermore, the unwinding table has an internal cavity, and the second and third air shafts are respectively fitted with a first gear and a second gear on the outside of the cavity. The first gear and the second gear mesh with each other. The outer wall of the unwinding table is equipped with a first servo motor and a second servo motor. The output end of the first servo motor is connected to the first air shaft, and the output end of the second servo motor is connected to the second air shaft.
[0017] The beneficial effect of adopting the above-mentioned further solution is that, by setting the first servo motor and the second servo motor, when the first servo motor and the second servo motor are working, the first air shaft and the second air shaft rotate synchronously in the same direction. At the same time, under the meshing action of the first gear and the second gear, the third air shaft rotates synchronously with the second air shaft, and the third air shaft and the second air shaft rotate in opposite directions.
[0018] Furthermore, the winding assembly includes a winding table, which is installed on the outer wall of the sewing table opposite to the unwinding table. A winding air shaft is rotatably connected to one side of the inner wall of the winding table. A third servo motor is installed on the outer wall of the winding table. The output end of the third servo motor is connected to the winding air shaft. The third servo motor, the second servo motor, and the third servo motor have the same rotation speed and the same direction of rotation.
[0019] The beneficial effect of adopting the above-mentioned further solution is that by setting a third servo motor, when the third servo motor is working, it is convenient to drive the third air shaft to rotate. At the same time, since the third servo motor, the second servo motor and the third servo motor have the same speed and the same direction of rotation, the tension of the battery sleeve is kept constant during the sewing process.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: The continuous production equipment for fireproof battery sleeves features staggered mounting grooves at both ends of the sewing table. An adjustment platform is installed inside each groove, and a sewing machine body slides onto the upper end of the adjustment platform. This allows the two sewing machine bodies to be staggered and opposite each other, sewing the two sides of the pressed upper fireproof material, fiberglass, and lower fireproof material. The two sewing machine bodies have the same sewing speed. The position of the sewing machine body can be adjusted using an electric slide rail and an electric slider to adapt to the production needs of battery sleeves of different widths. An edge detection sensor detects the side positions of the upper fireproof material, fiberglass, and lower fireproof material, and then drives the electric slide rail and electric slider to move the sewing machine body towards the center of the sewing table or towards the side of the sewing table based on the edge position detected by the edge detection sensor. This improves the versatility and production flexibility of the equipment. Attached Figure Description

[0028] Please see Figures 1-5This utility model provides a technical solution: a continuous production equipment for fireproof material battery sleeves, including an unwinding assembly 1, a winding assembly 2, a sewing assembly 3, and a pressing assembly 4. The sewing assembly 3 is disposed outside the unwinding assembly 1, the winding assembly 2 is disposed outside the sewing assembly 3, and the pressing assembly 4 is disposed above the sewing assembly 3. The sewing assembly 3 includes a sewing table 31, with mounting grooves 32 formed inside both ends of the sewing table 31. The two mounting grooves 32 are staggered, and an adjusting platform 33 is installed inside each pair of mounting grooves 32. A sliding groove 34 is formed inside each of the two adjusting platforms 33, and an electric slide rail 35 is installed inside each of the two sliding grooves 34. Two electric slide rails 35 are slidably connected to electric sliders 36 on their exteriors. A sewing machine body 37 is mounted on the upper end of each of the two electric sliders 36. A mounting base is mounted on the opposite end of each of the two sewing machine bodies 37. An edge detection sensor 38 is mounted on the bottom end of each mounting base. An embedding groove 39 is formed at the center of the sewing table 31. A pressure plate 310 is located directly above the embedding groove 39 at the upper end of the sewing table 31. Both ends of the pressure plate 310 are curved upwards, and connecting strips 311 are mounted on the outer walls of both ends of the pressure plate 310. The end of the connecting strip 311 furthest from the pressure plate 310 is fixedly connected to the top surface of the sewing table 31. The end of the connecting strip 311 furthest from the pressure plate 310 is fixedly connected to the top surface of the sewing table 31. The end of the connecting strip 311 furthest from the pressure plate 310 is fixedly connected to the top surface of the sewing table 31. One end of the plate 310 is curved upwards. Through the cooperation of the embedding groove 39, the pressure plate 310, and the connecting strip 311, the upper fireproof material, glass fiber, and lower fireproof material, which are easily pressed together, move forward through the space between the left end of the pressure plate 310 and the embedding groove 39 to the space between the middle of the pressure plate 310 and the embedding groove 39. At this time, the upper fireproof material, glass fiber, and lower fireproof material are tightly attached in the space between the middle of the pressure plate 310 and the embedding groove 39. By setting an edge detection sensor 38, the edge detection sensor 38 detects the side position of the upper fireproof material, glass fiber, and lower fireproof material. Then, the electric slide rail 35 and electric slider 36 are driven to work, so that the position of the sewing machine body 37 moves towards the center of the sewing table 31 or towards the side of the sewing table 31 according to the edge position detected by the edge detection sensor 38. After the positions of the two sewing machine bodies 37 are adjusted, the electric slide rail 35 and electric slider 36 are stopped. The two sewing machine bodies 37 are staggered and opposite to each other. The sewing speed of the two sewing machine bodies 37 is the same. They sew the two sides of the pressed upper fireproof material, glass fiber and lower fireproof material. The sewn strip battery sleeve moves forward continuously from the right end of the pressure plate 310 that is raised upward and the space between the embedded groove 39 until it is rolled up.
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1-5 This utility model provides a technical solution: the pressing assembly 4 includes two pairs of seats 41, which are respectively installed on the upper sides of the sewing table 31. A fixing block 42 is installed near the bottom of each pair of seats 41. A first rotating roller 43 is rotatably connected between a pair of fixing blocks 42 on the same side.

A slide bar is slidably connected inside the slide groove 34, and one side of the slide bar is fixedly connected to one side of the moving block 44. A threaded hole is provided inside the upper end of each of the two seats 41, and a screw 46 is threadedly connected inside the threaded hole. The bottom end of the rod 46 is connected to the side of the movable block 44 away from the fixed block 42 via a bearing. A knob 47 is installed on the end of the screw 46 away from the movable block 44. By rotating the knob 47, the screw 46 can be rotated, which can adjust the height of the movable block 44 and the second rotating roller 45, thereby adjusting the distance between the first rotating roller 43 and the second rotating roller 45 to accommodate fireproof materials of different thicknesses. At the same time, the cooperation between the slide bar and the slide groove 34 makes the movable block 44 rise and fall stably. Through the cooperation of the first rotating roller 43 and the second rotating roller 45, a stable upper and lower clamping force is formed on the upper fireproof material, glass fiber and lower fireproof material. When the material is conveyed to the sewing area, it can effectively prevent the material from shifting or slipping, and ensure that the material remains flat during the sewing process.
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figures 1-5This utility model provides a technical solution: the unwinding assembly 1 includes an unwinding table 11, which is installed on one side of the outer wall of the sewing table 31. A first air shaft 12 is rotatably connected to one side of the inner wall of the unwinding table 11. A second air shaft 13 and a third air shaft 14 are rotatably connected to the inner wall of the unwinding table 11 on the side of the first air shaft 12. The second air shaft 13 and the third air shaft 14 are arranged sequentially from top to bottom. A cavity is opened inside the unwinding table 11. The second air shaft 13 and the third air shaft 14 are respectively fitted with the first air shaft 13 and the third air shaft 14 in the cavity. A first gear 15 and a second gear 16 mesh with each other. A first servo motor and a second servo motor are mounted on the outer wall of the unwinding table 11. The output end of the first servo motor is connected to a first air shaft 12, and the output end of the second servo motor is connected to a second air shaft 13. The winding assembly 2 includes a winding table 21, which is mounted on the outer wall of the sewing table 31 opposite to the unwinding table 11. A winding air shaft 22 is rotatably connected to one side of the inner wall of the winding table 21. A third servo motor is installed on the outer wall. The output end of the third servo motor is connected to the take-up air shaft 22. The third servo motor, the second servo motor, and the third servo motor have the same speed and direction. The fiberglass core is placed on the first air shaft 12, and the upper fireproof material core and the lower fireproof material core are placed on the second air shaft 13 and the third air shaft 14 respectively. The empty take-up core is placed on the take-up air shaft 22. The fiberglass core, the upper fireproof material core, the lower fireproof material core, and the empty take-up core are installed. When the first servo motor... When the servo motor and the second servo motor are working, the first air shaft 12 and the second air shaft 13 rotate synchronously and in the same direction. At the same time, the meshing action of the first gear 15 and the second gear 16 causes the third air shaft 14 to rotate synchronously with the second air shaft 13. The third air shaft 14 and the second air shaft 13 rotate in opposite directions. When the third servo motor is working, it is convenient to drive the third air shaft 14 to rotate. At the same time, since the third servo motor, the second servo motor and the third servo motor have the same speed and the same direction, the tension of the battery cover is kept constant during the sewing process.
[0033] Specifically, the working principle of this continuous production equipment for fire-resistant battery sleeves is as follows: During use, the fiberglass core is fitted onto the first air shaft 12, the upper and lower fire-resistant material cores are fitted onto the second and third air shafts 13 and 14 respectively, and the empty winding core is fitted onto the winding air shaft 22. The fiberglass core, upper fire-resistant material core, lower fire-resistant material core, and empty winding core are then installed. One end of the upper fire-resistant material, fiberglass, and lower fire-resistant material is passed between the first rotating roller 43 and the second rotating roller 45 on the left side of the sewing table 31, and then passes through the pressure plate 310 and... Within the embedding groove 39, when the first servo motor and the second servo motor are working, the first air shaft 12 and the second air shaft 13 rotate synchronously in the same direction. Simultaneously, the meshing of the first gear 15 and the second gear 16 causes the third air shaft 14 to rotate synchronously with the second air shaft 13, but the third air shaft 14 and the second air shaft 13 rotate in opposite directions, unwinding the material. Through the combined use of the embedding groove 39, the pressure plate 310, and the connecting strip 311, and because both ends of the pressure plate 310 are curved upwards, the upper fireproof material, fiberglass, and lower fireproof material are easily compressed by the upward curvature of the pressure plate 310. The space between the left end and the embedding groove 39 moves forward continuously to the space between the middle of the pressure plate 310 and the embedding groove 39. At this time, the upper fireproof material, glass fiber, and lower fireproof material are tightly attached in the space between the middle of the pressure plate 310 and the embedding groove 39. By setting an edge detection sensor 38, the edge detection sensor 38 detects the side position of the upper fireproof material, glass fiber, and lower fireproof material, and then drives the electric slide rail 35 and the electric slider 36 to work, so that the position of the sewing machine body 37 moves towards the center of the sewing table 31 or towards the sewing machine according to the edge position detected by the edge detection sensor 38. After the platform 31 moves to the side and the positions of the two sewing machine bodies 37 are adjusted, the electric slide rail 35 and electric slider 36 stop working. The two sewing machine bodies 37 are staggered and opposite each other. The sewing speed of the two sewing machine bodies 37 is the same. They sew the two sides of the pressed upper fireproof material, glass fiber and lower fireproof material. The sewn strip battery sleeve moves forward continuously from the space between the right end of the pressure plate 310 and the embedded groove 39, and then is fixed on the take-up empty core. When the third servo motor works, it is convenient to drive the third air shaft 14 to rotate and take up the sewn material.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
