Description
Technical Field
[0001] The utility model relates to the field of film production equipment, and specifically relates to a unwind deviation rectifying device. Background Art
[0002] In the production of lithium batteries, the equipment for the electrode segment accounts for a relatively large proportion, basically about 44% of the overall manufacturing system, and plays a crucial role in the performance of the battery cells. Therefore, the research on the equipment for the electrode segment is of great significance for the production of lithium batteries. As the capacity of the energy storage battery cells is getting larger and larger, in order to reduce the material cutting and turnover times between the equipment for the electrode segment, the roll diameter and width of the material roll are getting larger and larger, and the electrode sheet will also be heavier and heavier. This will require higher and higher load-bearing capacity for the unwind shaft of the unwind deviation rectifying device. In order to prevent the unwind shaft from bending during long-term operation, in the prior art such as C211283093U disclosed on August 18, 2020, an unwind deviation rectifying device, fixed first vertical plates are provided at both ends of the unwind roll as supports to improve the strength of the unwind roll. However, this setting makes it very inconvenient to load and unload the material roll. Summary of the Utility Model

[0007] A support device, the support device is arranged at one end of the unwind shaft, the support device includes a second guide rail, the second guide rail is arranged along the axial direction of the unwind shaft; a third guide rail, the third rail is slidably connected to the second guide rail, the third guide rail is arranged vertically; a support member, the support member is slidably connected to the third guide rail, and the support member can rise along the third guide rail to abut against the end of the unwind shaft.
[0008] Through the above technical solution, when it is necessary to load and unload the material roll, the support member is lowered to a position that does not affect the loading and unloading, so as to facilitate the loading and unloading.
[0009] Further, the support member includes a support base, a first roller, and a second roller. The first roller and the second roller are rotatably connected to the support base. The first roller and the second roller are arranged oppositely. When the support member abuts against the unwind reel, the unwind reel is located between the first roller and the second roller, and the unwind reel abuts against the two rollers.

The fourth guide rail is slidably connected to the second guide rail, and the fourth guide rail is perpendicular to the second guide rail. The third guide rail is slidably connected to the fourth guide rail. By providing the fourth guide rail, the support member can move along the fourth guide rail along with the third guide rail, so that the support member avoids the loading area of the unwind reel, making the loading easier.
[0011] Further, the support device further includes a connecting member. One end of the connecting member is connected to the deviation rectifying actuator, and the other end of the connecting member is connected to the third guide rail or the fourth guide rail.

A slider is sleeved on the lead screw, and the slider is threadedly connected to the lead screw. The slider is provided with a first through hole, the guide rod passes through the first through hole, and the deviation rectifying sensor is fixedly connected to the slider.

[0019] 1. In this application, by setting a movable support member, when the unwinding shaft is working, the support member moves under the unwinding shaft to support the unwinding shaft to enhance its load-bearing capacity.

[0033] A connecting plate 26 is fixedly connected to the unwinding shaft 24, and two follower rollers 27 arranged at intervals are connected to the connecting plate 26. The axial direction of the follower rollers 27 is parallel to that of the unwinding shaft 24, and the follower rollers 27 can rotate around themselves relative to the connecting plate 26.
[0034] The pole pieces of the coil wound on the unwinding shaft 24 sequentially pass through the two follower rollers 27. The pole pieces can be tensioned by the follower rollers 27.
[0035] The first base 21 is connected with a linear bearing 211, and a guide shaft 212 is arranged inside the linear bearing 211. The guide shaft 212 is fixedly connected to the connecting plate 26. The weight of the connecting plate 26 and the follower rollers 27 is supported by the guide shaft 212, and at the same time, the load-bearing capacity of the unwinding shaft 24 is also enhanced.
[0036] Three second through holes are provided on the fixing plate 1, and the unwinding shaft 24 and the two follower rollers 27 respectively pass through the second through holes. A bracket 41 of the deviation rectifying device 4 is connected to the fixing plate 1 at a position between the two follower rollers 27. A lead screw 42 and a guide rod 43 parallel to each other are connected to the bracket 41. A slider 44 is sleeved on the lead screw 42, and the slider 44 is threadedly connected to the lead screw 42. The slider 44 is provided with a first through hole, and the guide rod 43 passes through the first through hole. A deviation rectifying sensor 45 is fixedly connected to the slider 44. The position of the deviation rectifying sensor 45 can be adjusted by the lead screw 42 and the slider 44, so as to adapt to coils of different widths.

[0038] The deviation rectifying device 4 further includes a deviation rectifying actuator 47 fixedly connected to the fixed plate 1, and the driving end of the deviation rectifying actuator 47 is fixedly connected to the unwinding shaft 24.
