Description

Technical Field

[0001] The utility model relates to the technical field of repair tools for lithium battery unwinding and drying equipment, in particular to a roller changing device for lithium battery unwinding and drying equipment. Background Art

[0002] Lithium battery unwinding and drying equipment is a device used to process lithium battery materials, mainly used to remove moisture from lithium battery materials. Among them, this equipment is usually composed of an uncoiler, a drying tower, a traction device, a winder, etc. Specifically, first, the uncoiler is a device used to unfold lithium battery materials, usually using hydraulic or pneumatic pressure to unfold the materials. Second, the drying tower is the core part of the equipment, which removes moisture from the material through heating and ventilation. Third, the traction device is used to pull the material to the drying tower and pull it out of the drying tower after drying. Fourth, the winder is used to wind the dried lithium battery material into a coil of a certain specification. More specifically, the use of lithium battery unwinding and drying equipment can effectively remove moisture from lithium battery materials and improve their performance and service life. At the same time, this equipment can also be customized according to different materials and process requirements to meet the needs of different production lines.

[0003] The winder usually drives the coil to roll on the outer surface by rotating rollers, forming a roller structure with the roller in the middle and the coil on the outside. Then the staff needs to disassemble the roller structure formed by the roller and the coil from the winder and transfer it to the coil support device to separate the lithium battery coil and the roller structure, thereby obtaining the dried and sorted coil. It should be noted that the roller structure formed by the coil and the roller is cylindrical as a whole, and its volume is large and its weight is heavy. In the production process, for disassembling the roller structure from the winder, it is generally supported by multiple people cooperating with each other to support the roll structure. In the specific disassembly process, due to the large volume, heavy weight and small disassembly space of the roller structure, the disassembly efficiency is slow. The roller structure supported by manual cooperation is very likely to shake during the disassembly process due to the long disassembly time and limited human endurance, resulting in low disassembly efficiency. There is even a risk that the shaking may squeeze the workers, so there is a certain risk factor for the workers. For this reason, it is necessary to propose a roller changing device for lithium battery unwinding and drying equipment. Utility Model Content

[0013] In one possible implementation, the guide rail member includes a first guide rail and a second guide rail that is locked and connected to one end of the first guide rail. The other end of the first guide rail is connected to the roller changing frame, and the end of the second guide rail away from the first guide rail is used for plugging in the roller structure.

[0014] In one possible implementation, the limiting member includes a limiting block located above the second guide rail and pins located at both ends of the limiting block.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] It should be noted that, since the roller structure is large in size and heavy in weight as a whole, and the existing disassembly method generally relies on multiple people to cooperate to support the roller structure, and due to the limited endurance of the workers and the long disassembly time, when the roller structure is disassembled by this disassembly method, the manual support stability of the roller structure is poor, thereby reducing the disassembly efficiency of the roller structure. At the same time, for the workers, the safety risk factor is relatively high when supporting the roller structure. For this reason, the utility model proposes a roller changing device for lithium battery unwinding and drying equipment to improve the above problems.

[0023] It needs to be explained that the roller structure includes a rotating roller and a coiled material, and also includes a transfer frame. The two ends of the rotating roller pass through the two ends of the transfer frame and are rotatably connected to the winder. The two ends of the rotating roller are rotatably connected to the transfer frame, and the transfer frame and the winder are detachably connected. The transfer frame is used to be detachably connected to the roller changing device. Specifically, the roller changing device transfers the rotating roller and the coiled material together to the coil supporting device by plugging in the transfer frame, and the coil supporting device separates the coiled material and the rotating roller.

[0024] like Figure 1 and Figure 2As shown, a roll changing device for lithium battery unwinding and drying equipment includes a roll changing frame 10, a support assembly 20 and a lifting assembly 30. The mixed roll frame can serve as a main body support as a whole. The support assembly 20 is provided on the upper end surface of the roll changing frame 10, and the support assembly 20 is connected and fixed to the roll changing frame 10. The lifting assembly 30 is provided on the lower end surface of the roll changing frame 10, and the lifting assembly 30 is connected and fixed to the roll changing frame 10. The support assembly 20 is used to abut against the roll structure and support the roll structure. The lifting assembly 30 is used to contact the ground and is used to move the roll changing frame 10 horizontally and lift it vertically. The lifting assembly 30 drives the support assembly 20 and the tube roll frame to move in the horizontal direction and in the lifting direction, so that the utility model can support the disassembled roll structure through the lifting assembly 30, instead of manually supporting the roll structure. Compared with manual support, the support structure of the roll structure of the utility model is more stable and safer.

[0025] For further reference, Figure 1 and Figure 2 The lifting assembly 30 includes a moving member 31, which is fixedly connected to the roller changing frame 10. The moving member 31 is used to support and slide the roller changing frame 10 in a horizontal moving state.

[0026] In this embodiment, reference Figure 1 The lifting assembly 30 includes 6 moving parts 31, wherein the moving parts 31 can be universal wheels or casters, etc. In this embodiment, the moving parts 31 are not further limited. The lower end surface of the lifting assembly 30 is rectangular, and the 6 moving parts 31 are symmetrically arranged on both sides of the lower end surface of the lifting assembly 30. The moving parts 31 and the lifting assembly 30 are fixed by bolts. The structural setting of the moving parts 31 can make it easier to push the roller changing frame 10 and the lifting assembly 30 to move in the horizontal direction, and support both.

[0027] For further reference, Figure 1 and Figure 2 The lifting assembly 30 includes a lifting member 32 and a support plate 33, the lifting member 32 is connected to the support plate 33, the moving member 31 is connected to the support plate 33, and the lifting member 32 and the moving member 31 are arranged linearly, wherein the support plate 33 is connected and fixed to the roller changing frame 10.

[0028] In this embodiment, the lifting assembly 30 includes 6 lifting members 32 and 6 supporting plates 33 matched therewith, wherein the supporting plates 33 are located above the lifting members 32, and the 6 supporting plates 33 are symmetrically arranged on both sides of the roller changing frame 10, and the supporting plates 33 are bolted and fixed to the roller changing frame 10. In addition, the lower end surface of the support plate 33 is rectangular, and the lifting members 32 and the moving members 31 are respectively arranged at both ends of the support plate 33, and the lifting members 32 and the moving members 31 are both connected and fixed to the support plates 33 by bolts. Through the structural setting of the support plates 33, the lifting members 32, the moving members 31, and the support plates 33 can be assembled in advance, which improves the assembly efficiency of the utility model to a certain extent. More specifically, the lifting members 32 can be adjustable foot cups, wherein the lifting members 32 are used to support and lift the roller changing frame 10 and the support assembly 20, thereby improving the support stability of the load-bearing roller structure of the utility model.

[0029] It should be explained that the roller structure includes a rotating roller and a coil, which together make the overall shape and volume of the roller structure larger and heavier, resulting in a certain downward impulse of the roller structure at the moment of separation from the winder, and the impulse is transmitted to the movable part 31 below the support assembly 20 and the roller changing frame 10. However, due to the poor horizontal stability of the movable part 31, the roller changing frame 10 and the support assembly 20 appear to shake horizontally. Specifically, the utility model moves the roller changing frame 10 and the support assembly 20 to the bottom of the roller structure through the movable part 31. In some embodiments, the roller changing frame 10 can be adjusted in height to support the roller structures at different heights. Since the movable part 31 has a certain sliding force on the horizontal plane, Inertia, for this reason, through the structural setting of the lifting member 32, the utility model can be moved to the bottom of the roller structure, and then the lifting member 32 is lowered to contact the ground, thereby raising the roller changing frame 10, the support assembly 20 and the moving member 31 until the support assembly 20 contacts the roller structure and the moving member 31 is separated from the ground. The lifting member 32 replaces the moving member 31 to contact the ground, which increases the gripping area of ​​the utility model and improves the stability of the utility model. Furthermore, through the structural setting of the lifting member 32, the impact force of the roller structure on the downward fall can be effectively resisted, so that the impact force of the roller structure is transmitted from the lifting member 32 to the ground, reducing the movement of the utility model on the horizontal plane and improving the stability of the utility model.

[0030] For further reference, Figure 1 and Figure 2 The support assembly 20 includes a guide rail member 21 and a limiting member 22 located above the guide rail member 21. One end of the guide rail member 21 is used to connect with the roller structure, and the limiting member 22 is used to limit the roller structure after connection. The other end of the guide rail member 21 is connected to the roller changing frame 10.

[0031] In this embodiment, the support assembly 20 includes two guide rails 21 and two limit members 22. Specifically, the axial direction of the guide rail 21 is parallel to the longitudinal direction of the roller changing frame 10. The guide rail 21 is located on the upper end surface of the roller changing frame 10. By adjusting the height of the lifting member 32, the guide rail 21 is adapted to the height of the roller structure. By pushing the roller changing frame 10 in combination with the structural setting of the moving member 31, the guide rail 21 slides to the roller structure, and one end of the guide rail 21 is plugged into the roller structure. , combined with the other end connected and fixed to the roller changing frame 10, the guide rail member 21 supports the roller structure separated from the winder. To be more specific, the two guide rail members 21 are both located on the upper end surface of the roller changing frame 10 and are arranged in parallel, and the two limit members 22 are located above the guide rail members 21, wherein the longitudinal direction of the limit member 22 and the axial direction of the guide rail member 21 are arranged perpendicular to each other. In addition, after the roller structure is plugged in and supported, the roller structure on the guide rail member 21 is limited and fixed by the limit member 22.

[0032] For further reference, Figure 1 and Figure 2 The guide rail member 21 includes a first guide rail 211 and a second guide rail 212 that is locked and connected to one end of the first guide rail 211. The other end of the first guide rail 211 is connected to the roller changing frame 10, and the end of the second guide rail 212 away from the first guide rail 211 is used for plugging in the roller structure.

[0033] In this embodiment, the two first guide rails 211 are respectively located on both sides of the roll changing frame 10. Specifically, the two sides of the upper end surface of the roll changing frame 10 are respectively provided with guide rail seats adapted to the first guide rails 211. The lower end surface of the guide rail seat abuts against the roll changing frame 10 and is fixed by bolt connection. The upper end surface of the guide rail seat is provided with a mounting concave surface. The first guide rail 211 is installed in the mounting concave surface and is fixed by screw connection. Further specifically, the second guide rail 212 is located on the extension line of the first guide rail 211, wherein One end of the first guide rail 211 is provided with a positioning circular groove, and the end of the second guide rail 212 close to the first guide rail 211 is provided with a positioning cylinder adapted to the positioning circular groove. Through the structural setting of the positioning circular groove and the positioning cylinder, the first guide rail 211 and the second guide rail 212 can be connected in a detachable manner. In this embodiment, the height of the roller changing frame 10, the first guide rail 211, and the second guide rail 212 is adjusted by the lifting member 32, so that the second guide rail 212 is away from the first guide rail 211 One end of is adapted to the roller structure and plugged into the roller structure, thereby completing the support of the roller structure. It needs to be explained that the roller structure includes a transfer frame, and the transfer frame is provided with two plug-in holes adapted to the second guide rail 212. After adjusting the height of the second guide rail 212 to make it dock with the plug-in hole, the second guide rail 212 is inserted into the plug-in hole by pushing the roller changing frame 10 and the moving part 31, and then the utility model is stabilized by the lifting part 32. Then, after the roller structure as a whole is separated from the winder, it is transferred from the second guide rail 212 to the first guide rail 211 by pushing the roller structure, and is located directly above the roller changing frame 10. Finally, the roller structure is limited by the limiting part 22, and the lifting part 32 is removed, and the roller changing frame 10 is transferred by the moving part 31, so that the utility model disassembles the roller structure on the winder and transfers it to the winding equipment. In this process, the support of the roller structure of the utility model is higher in support stability and safety factor than manual support.

[0034] It should be added that the first guide rail 211 and the second guide rail 212 are connected in a detachable manner, so that after the roller structure is pushed from the second guide rail 212 to the first guide rail 211, the second guide rail 212 can be removed from the first guide rail 211, shortening the length of the roller changing frame 10, thereby making it easier to rotate and move the present invention.

[0035] For further reference, Figure 1 and Figure 2 The limiting member 22 includes a limiting block 221 located above the second guide rail 212 and pins 222 located at both ends of the limiting block 221. Pin holes 223 matching the pins 222 are respectively provided at both ends of the limiting block 221. The pins 222 are used to insert into the pin holes 223 to limit the roller structure.

[0036] In this embodiment, the limiting member 22 includes two limiting blocks 221, and the two limiting blocks 221 are respectively arranged perpendicular to the two ends of the two second guide rails 212. Specifically, the two ends of the limiting block 221 are respectively provided with a pin hole 223 connecting the upper end face and the lower end face of the limiting block 221. The latch 222 is used to pass through the pin hole 223, thereby limiting the roller structure to prevent the roller structure from sliding along the first guide rail 211. Further specifically, limiting ears corresponding to the pin hole 223 and the pin shaft are provided on both sides of the roller changing frame 10. In addition, limiting ears corresponding to the pin hole 223 and the pin shaft are also provided on both sides of the transfer frame of the roller structure. The hole 223 and the limiting ear correspond to the limiting hole. After the roller structure is pushed from the second guide rail 212 to the first guide rail 211, the position of the transfer frame is adjusted to make the limiting hole correspond to the limiting ear. Then the limiting block 221 is set above the roller structure, and the pin shaft is passed through the pin hole 223 and the limiting block 221 in sequence and then connected to the limiting ear, so that the limiting block 221 and the pin shaft limit and fix the roller structure placed on the first guide rail 211, avoiding sliding in the process of transferring the roller structure from the winder to the winding device, thereby improving the transfer stability of the roller structure of the utility model.

[0037] For further reference, Figure 1 and Figure 2 The roller changing device also includes a first buffer 40 and a second buffer 50. The first buffer 40 is connected to the side surface of one end of the roller changing frame 10, and the second buffer 50 is connected to the upper end surface of the roller changing frame 10. The first buffer 40 and the second buffer 50 are both used to buffer the movement of the roller structure.

[0038] In this embodiment, reference Figure 1 and Figure 2The roller changing device includes two first buffers 40 and two second buffers 50, wherein the two first buffers 40 are located at one end of the roller changing frame 10 and are fixed with the side bolts of one end of the roller changing frame 10. When the roller structure moves from the second guide rail 212 to the first guide rail 211, the first buffer 40 is used to abut and buffer the lower end surface of the roller structure, thereby preventing the transfer frame of the roller structure from directly colliding with the roller changing frame 10. In addition, the two second buffers 50 are located at the other end of the roller changing frame 10 and above the roller changing frame 10. Specifically, the second buffer 50 includes a buffer block and a folding plate connected to the buffer block. One end of the folding plate is in contact with the upper end surface of the roller changing frame 10 and is fixed by screws, and the other end of the folding plate is fixed by screws to the buffer block, so that the buffer block is suspended above the roller changing frame 10. When the roller structure moves from the second guide rail 212 to the first guide rail 211, the structural setting of the second buffer 50 can prevent the coiled material and the rotating roller of the roller structure from directly colliding with the roller changing frame 10. At the same time, the structural setting of the first buffer 40 and the second buffer 50 can also buffer the shaking of the roller structure in the process of transferring the roller structure from the winder to the winding device, thereby preventing the roller changing frame 10 from colliding and wearing the roller structure.

As long as various improvements are made using the method concept and technical solution of the present utility model patent, or the concept and technical solution of the present utility model patent are directly applied to other occasions without improvement, they are all within the scope of protection of the present utility model.
